yeah I have a thought, she wanted to have sex except you didn't close the deal and just "cuddled" so she got bored and then left, she probably would have had sex and slept over.
Don't be afraid to initiate sex, in fact you should initiate sex, if you get rejected and are told "NO", that's ok and respect her when she tells you NO, but you had your wife come home after a long day of work unexpectedly and take off all her clothes and climb into bed with you to be near you.
Yep. this ^
There's a running gag that I started on the forum that any man who uses the word "cuddle" in their posts, probably won't successfully DB their marriage, and any man who actually uses it with his WIFE, definitely won't.
It was meant more as an observation than a joke, but I think there's a lot of truth in it.
